The wall-mounted boiler is a modern household heating device that is usually installed on the wall, hence the name "wall-mounted boiler." Under normal circumstances, the wall-mounted boiler can provide warmth and hot water for the home. So, how can we resolve the E2 fault in a wall-mounted boiler?
How to recover from the E2 fault in a wall-mounted boiler:
1. Clean the water pump
Cleaning the water pump is the first step in recovering from the E2 fault in the wall-mounted boiler. Typically, the water pump can malfunction due to blockages from dust or debris. Therefore, we can open the boiler's panel, locate the water pump, and then clean around the water pump and the pump itself with clean water. When cleaning the pump, it is important to disconnect the power supply and wait until the boiler has completely cooled down to avoid accidents. Cleaning the water pump is a simple and effective method that can help resolve some E2 faults caused by water pump issues.
2. Check the water pump's working status
If the E2 fault code still appears after cleaning the water pump, we need to check the functioning status of the pump. Typically, the water pump emits noise; if we do not hear the normal operational sounds, it indicates that the pump may be faulty. In this case, we need to disconnect the power, remove the water pump, and use a multimeter to measure the resistance and insulation of the pump. If there are obvious resistance abnormalities or insufficient insulation, the pump needs to be replaced.
3. Adjust the water pressure
Sometimes, the E2 fault in the wall-mounted boiler is caused by inadequate working pressure from the water pump. Therefore, we can adjust the pump's working pressure to resolve this issue. Usually, there is a pressure adjustment valve on the boiler that we can gently turn with a screwdriver, and then wait for a while to allow the boiler to return to normal operation. Adjusting the water pressure is a simple and effective way to address some E2 faults caused by insufficient water pressure.
4. Check the water supply system
The E2 fault in the wall-mounted boiler may also be due to problems in the water supply system. We should check the supply pipes and valves of the boiler to see if there are any blockages or leaks. If any issues are found in the water supply system, they need to be repaired promptly, and the boiler should be restarted.
In summary, the steps for recovering from the E2 fault in a wall-mounted boiler have been introduced here. The E2 fault is a common type of malfunction, typically caused by issues with the water pump. When the E2 fault occurs, we can take some steps to recover, such as cleaning the water pump, checking the pump's operational status, adjusting the water pressure, and inspecting the water supply system. If none of these methods resolve the problem, it is advisable to contact a professional repair technician for assistance. I hope this information is helpful and enables everyone to better handle E2 fault issues in wall-mounted boilers.
